Following a dismal high school reunion and a disastrous proposal of marriage, a going-nowhere twentysomething (Keira Knightley) falls in with a carefree teenager (Chloë Grace Moretz) and takes a week off to reassess her life.

Overeducated and underemployed, 28-year-old Megan is in the throes of a quarter-life crisis. Squarely into adulthood with no career prospects or motivation to think about her future, Megan is comfortable lagging a few steps behind while her friends check off milestones and celebrate their new grown-up status. When her high-school sweetheart proposes, Megan panics and — given an unexpected opportunity to escape for a week — hides out in the home of her new friend, 16-year-old Annika, and her world-weary single dad Craig. A romantic coming-of-age comedy about three people who find their lives intertwined in the most unconventional of ways.
